| 5 | # This module adds support to testimage.bbclass to deploy images and run | ||
| 6 | # tests on a BeagleBone (original "white" or Black models). The device must | ||
| 7 | # be set up as per README.hardware and the master image should be deployed | ||
| 8 | # onto the card so that it boots into it by default. For booting into the | ||
| 9 | # image under test we interact with u-boot over serial, so for the | ||
| 10 | # BeagleBone Black you will need an additional TTL serial cable since a | ||
| 11 | # serial interface isn't automatically provided over the USB connection as | ||
| 12 | # it is on the original BeagleBone ("white") version. The separate ext3 | ||
| 13 | # partition that will contain the image to be tested must be labelled | ||
| 14 | # "testrootfs" so that the deployment code below can find it. | ||
| 15 | # | ||
| 16 | # NOTE: for the BeagleBone "white" (original version) you may need to use | ||
| 17 | # a script which handles the serial device disappearing on power down, such | ||
| 18 | # as scripts/contrib/serdevtry in OE-Core. | ||
